Relay UE Paging Using Identity Mapping for Idle Remote UEs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing paging methods for remote UEs in an idle state are inefficient, leading to high resource overheads as the access network device cannot determine the relay UE, resulting in the need to send paging messages to all UEs providing relay services within coverage.
Innovation Solution
The access network device maintains and utilizes identity information of remote UEs in idle states to determine the corresponding relay UE, allowing targeted paging messages to be sent directly to the appropriate relay UE, thereby optimizing resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the access network device sends paging messages to all UEs providing relay services within coverage, then the remote UE can be paged reliably, but resource overhead increases significantly
Solution Approach 1:
The patent segments the paging process by introducing identity information that divides UEs into groups based on their relay service relationships. The access network device maintains identity information mapping remote UEs to their serving relay UEs, allowing the paging message to be segmented and directed only to the specific relay UE that should receive it, rather than broadcasting to all relay UEs.
Solution Approach 2:
The patent changes the parameter of paging message targeting by incorporating identity information (such as remote UE ID or relay UE ID) into the paging message. This parameter change enables the access network device to identify and page only the specific relay UE associated with the remote UE, transforming the paging mechanism from a broad broadcast to a targeted communication.
2Productivity
If the access network device maintains identity information of remote UEs, then targeted paging is enabled, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by having the access network device maintain identity information mapping before the paging operation occurs. The identity information (linking remote UEs to relay UEs) is established and stored in advance during the relay service setup phase, so that when paging is needed, the device can immediately query and use this pre-maintained information to target the correct relay UE without complex real-time determination.
3Ease of operation
If paging messages are sent to all relay UEs, then no relay UE information is needed, but resource utilization decreases
Solution Approach 1:
The patent introduces identity information as an intermediary element that mediates between the access network device and relay UEs. This identity information acts as a key or pointer that enables the access network device to efficiently determine which relay UE should receive the paging message, serving as a intermediary lookup mechanism that simplifies the operation while improving resource utilization compared to broadcasting to all relay UEs.

AI summary
Provided in the embodiments of the present application are a paging method, a device, and a storage medium. The method comprises: an access network device receiving a message A from a core network node or a second terminal device, wherein the message A comprises first identification information, and the first identification information is used for identifying a first terminal device; and according to the first identification information, the access network device sending, to the second terminal device, a paging message for paging the first terminal device, wherein the second terminal device provides a relay service for the first terminal device. Therefore, the resource utilization rate is improved.
